Chapter 7 Maintaining Your Cisco 7513, Cisco 7513-MX, and Cisco 7576 Router
Maintenance Procedures for the Cisco 7513, Cisco 7513-MX, and Cisco 7576
Note
If you plan to replace your existing card cage assembly with a new one, you must first perform the
procedure in the
“Exchanging the EEPROM Devices” section on page 7-7
before you install your new
card cage assembly. However, if you simply plan to remove your card cage assembly and then reinstall
it, you do not need this procedure; instead, proceed to the
“Installing the Card Cage Assembly” section
on page 7-9
.
Exchanging the EEPROM Devices
The following procedure requires you to first exchange the blank EEPROM devices on your new card
cage for the old EEPROM devices from your old card cage, and then place the blank EEPROM devices
on your old card cage for return to Cisco Systems.
Note
You do not need to perform this procedure if you do not plan to install a new card cage assembly;
however, if you do plan to install a new card cage assembly, you must exchange the new electrically
erasable programmable read-only memory (EEPROM) devices on the rear of the new card cage for the
old EEPROM devices on the rear of your old card cage.
The EEPROM devices on your old card cage have MAC addresses programmed into them, which are
necessary for your system to function properly, and these old EEPROM devices are therefore required
for your system to operate properly with a new card cage assembly.
Note
Do not perform these steps if you are upgrading a Cisco 7513 to a Cisco 7576. These instructions apply
only to the replacement of an equivalent model card cage.
Caution
To prevent system problems after installation, note that the new EEPROM devices that shipped on your
new card cage are blank and must be replaced if you plan to replace your card cage with a new one.
For this procedure, you will need a small piece of masking or cellophane tape to mark the new EEPROM
devices as blank. (The old card cage is assumed to have already been removed from your Cisco 7513,
Cisco 7513-MX, or Cisco 7576 using the procedure in the
“Removing the Card Cage Assembly” section
on page 7-5
.)
Use the following procedure to exchange the EEPROM devices:
Step 1
Attach an ESD preventive wrist strap between you and an unpainted surface of the Cisco 7513, Cisco
7513-MX, or Cisco 7576 chassis.
Step 2
Locate the blank EEPROM devices, located on the rear of the new card cage near the chassis interface
board(s). (See
Figure 7-5
for the Cisco 7513 and Cisco 7513-MX, and
Figure 7-6
for the Cisco 7576.)
Step 3
Remove the blank EEPROM devices from the new card cage, place a piece of tape on them to mark them
as blank EEPROM devices, and set them aside.
Step 4
Locate the old EEPROM devices, located on the rear of your old card cage. (See
Figure 7-5
for the Cisco
7513 and Cisco 7513-MX, and
Figure 7-6
for the Cisco 7576.)
